Application and September 2,1905. sum-nearer.

lt, known that I, AmoN'SonmFnas'rnm,

a citizen of the United-States, and a resident of Bayonne, in the county of Hudson and State ofiNew Jersey have invented certain new and useful Improvements in Gas-Em.

pressor or air pump, operating in conjunction with and forming part ofanengine', the said pom ressor or air pump having in its moving in amsm a pair ofe liptic-gears, to enable the charge from the air pumpto enter the working cylinder of the en ine, during its discharge of spent, gases. 'lhe elliptic gears.

drive the compressor piston on its up-strokes at about-the same speed as the speed of the piston in the working cylinder of the, engine.

the drawings the invention is shown with a' four 0 ch engine. Y I Figure 1 s ows an elevation and partial section-of the invention, Fig. 2 is a section of Fig. 1 on the line 2:, 2:, Fig. 3 represents an end view of Fig. 1.-

An air pump or compressor cylinder A, has mounted thereon the head B, containing the usual inlet valve B','with its inlet pipe (Ila-11d outlet valve B with its outlet ipe l). The cylinder is supported on the mine E, and contains the piston A. The latter is joined with the connecting rod 1*", which is actuated b means of the wrist pin F'extending' from g nes of which the following is a speeifica-- spentgases and the like. ciaracterized by a. coni-' e elliptic gear G at its rea'elving focus. The

said gear is supported on the shaft G whose axis is in line with the stationary focus of said Esar, the shaft G being supported by the hub An elliptic gear H meshes with the gear G, and is supported on the shaft ll passing through'its stationary focus, and which in the resent case is in the same horizontal plane with the shaft G. The shaft H is supported in the bearings H.

Ad'aeent to the frame E and connected thereto by the connecting portions II, is the frame J of the engine, that is to co-act with the air pump, and in this case is represented as a gas en inc, having the cylinder K With the piston C, head L, and. exhaust 'valve chamber M", with the exhaust valve M. -='-Withih the time J'are the am utmi 's J; J for their-rank shaft N, that is :ioined'withthe eonnectin rod-N;-. and which atter is connected with t 1e piston K. The said crank shaft has mounted thereon the pinion N-, which lneshes'with agear I fastenedto the shaft H, and is,-in. this case,

aboutdouble the diameter of the said pinion.

Qn the shaft N is'also secured the bevel pin ion 0, that meshes with the bevel gear 0',

which latter is fastened to the vertical shaft P carrying the bevel ear Q. The latter bevel wheel meshes wit 1 the gear Q on the shaft-1 11, fthat carries. a, eani R, which actuates the valve spindle of the exhaust valve M.

A gas inlet valve. for the cylinder K is shownat 1 0 with the gas inlet pipe 11. A spark plug,12 is connected to the head L and is in circuit with the battery 14- by means of the wire 15. A wire 17 leads to an insulated pin 18. A spring 19 with the terminal 20 is actuated by a cam 21 to open and close the circuit for the spark plug 12. a

For a two cycle gas engine, the pinion- N and gear wheel I would be made of approxi-' mately equal diameters.

The outlet pipe 1) of the compressor or air pump connects with the cylinder K. and has a check valve V, ad acent to the cylnnler h.

When operating the invention the gas engine drives the cmnpre-=s w through the train of gearing as shown. -l he pinion makes two revolutions for each revolution of the wheel I, urn l. (TIC elliptic gears are propox-tinned so that the up stroke of the air pump piston. is made in shout the same interval of time, as every second up stroke ol" the gas engine, so that the air from iliifuillpre sor enters the cylinder of the gas 'engine when the latter is ore}: to the exhaust.

The exhaust valve oi the gas engine opens at about the eon;niencezm-nt ol' every second up stroke of its piston, and the air or other gas from the air pump will he lnl't'tli therein at the proper time. to cool and cit-an the cylinder of thc'gas engine of its spent gases.

raving described my invention, '1 claim:

l. The comh'inntimi with a gas engine of an. air pump. a conduit connecting the outlet of the air pump and the cylinder of the engine, a shaft for the engine and. a shaft for the air pump, a pair of elliptic gears connected up between said shafts so that the discharges from the air pump will be forced into the c linder of the engine during the intervals t at the spent gases are exhausted from the latter.

2. The combination with a gas engine of 5 an air pump, a pipe connecting the disbharge opening of the air pump and the c" linder of the gas engine, a crank shaft for t e engine, a pinion on said shaft, a crank shaft for the air pum a third shaft between said- 10 shafts, a gear w eel on the third shaft mesh- A sixth day of Au BEST AVAILABLE copy witheach other, and proportioned so that each upstroke of the air pump will be made in the same interval of time as eirery second up strokeiofithe engine, to force air from the am pump into the cylinder of the engine when the latter is exhausting its spent Signed at Bayonne, in the county of son and vState of New Jersey this twentyc, A.
